# Tube-to-tube contact elements

 Tube-to-tube elements: model the finite-sliding interaction between two pipelines or tubes where one tube lies inside the other or between two tubes or rods that lie next to each other; are slide line contact elements, in the sense that they assume that the relative motion of the two tubes or pipes is predominantly along the line defined by the axis of one of the tubes (the relative rotations of the tube or pipe axis are assumed to be small); can be used with pipe, beam, or truss elements; and do not consider deformations of the tube or pipe cross-section. Defining Contact Interactions contains a general discussion of contact modeling. The following topics are discussed:
